Ethernet, serial-data multiplexer integrates utility fiber-optic
A new Ethernet and serial-data unit from TC Communications multiplexes one 10/100M Ethernet and four channels of RS-232, RS-422, TTL, or dry contact interfaces over single- or multi-mode fiber. A one fiber, two-way-communication option doubles existing fiber utilization.
TC8530 is a way to integrate substation networks with RTUs and PLCs with Ethernet and Serial interfaces over a single fiber. Service providers also use the TC8530 as a cost effective way to provide Ethernet and serial connections, the company says.
It supports distances exceeding 100 km and offers redundant power and optics, including automatic switchover features for maximum reliability. It is available “industrial hardened”, -40 to 80 degrees C, for extreme environments.
The Ethernet port auto-negotiates at 10/100M, with full 10Mbps throughput, and enables rate control in increments of 32 Kbps. It is IEEE 802.3/802.3u/802.3x compliant. Setup, diagnostics and control are accessed via serial terminals, telnet, or SNMP management-ports.

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
